Enrijecer células cancerígenas potencializa a terapia com células CAR-T em camundongos

Pesquisadores descobriram que tornar as células cancerígenas mais rígidas pode aumentar a eficácia da terapia com células CAR-T contra tumores agressivos. Em experimentos com camundongos, a abordagem levou ao desaparecimento completo do tumor em alguns casos. As descobertas foram apresentadas recentemente em uma conferência em Londres.

As células cancerígenas costumam ser mais macias que as saudáveis devido a níveis mais elevados de colesterol em suas membranas. Essa maciez pode ajudá-las a escapar de ataques imunológicos. Cientistas do Instituto Federal de Tecnologia de Lausanne, na Suíça, testaram se o enrijecimento dessas células poderia melhorar os resultados da imunoterapia.

A 47-year-old woman bedridden with autoimmune hemolytic anemia, immune thrombocytopenia, and antiphospholipid syndrome has achieved complete remission after CAR-T cell therapy at University Hospital Erlangen in Germany. Treated by Fabian Müller after nine failed therapies, she recovered rapidly and remains healthy over a year later without medication—the first simultaneous treatment of multiple autoimmune diseases with this method.

Researchers tested a redesigned CD40 agonist antibody, 2141-V11, by injecting it directly into tumors of 12 patients with metastatic cancers. Six patients saw tumor shrinkage, with two achieving complete remission, including effects on untreated tumors elsewhere in the body. The trial reported only mild side effects, unlike prior CD40 therapies.
